Is it better to have a vented or sealed crawl space?

• <div><p>It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible. </p></div>

Q: Can underfloor insulation cause moisture and mold?

• <div><p>Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and&mdash;if your floors are wood&mdash;rotting.</p></div>

Q: How can I protect my house from a sump pump failure?

• <div><p>Thankfully, you do have a few <a href="https://www.angi.com/articles/how-keep-your-sump-pump-running.htm">sump pump backup options</a> in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. </p><p>Or you can opt for a water-powered backup pump, which uses your home&rsquo;s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.</p></div>

Q: How often do you need to clean your crawl space?

• <div><p>Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.</p></div>

Q: Should I avoid buying a house with a crawl space?

• <div><p>Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn&rsquo;t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn&rsquo;t have any more issues than a slab or basement home.</p></div>
